Get rich by doing something you love to do and do it extremely well.
Whatever it is, you'll be happy doing it, and being rich won't be as important.
There is a statement for that, I remembered my teacher saying that you must choose what do you want a job or a career. A job is where you get paid a large amount of money not doing what you want while a career is where you do what you want and get paid less. Either way its different than each other. You are lucky if you are being paid well by doing what you want.
